' Application filed April 23, 1902.;

To all whom it may concern.-

Apparatus, of which improvements the following is a specification.

' The invention described herein relates to certain improvements inmechanism for forg ing car-axles, &c., and has for its object aconstruction and arrangement of parts where by the article being forgedmay be turned axially from time .to time and shifted from oneshaping-matrix to another as the forging proceeds.

The invention is hereinafter more fully described'and claimed. g Y

In the accompanying drawings, forming a part of this specification,Figure'l is a view in elevation of my improved mechanism. Fig. 2 is aplan view of the same, the upper forgingdie and its operating mechanismbeing removed. Fig. 3 is a view, partly in section and partly inelevation, showing the forging-dies and the shifting and turningmechanism. Fig. 4. is a sectional view, on a large scale, of the valvemechanism controlling the shifting and. turning devices. Fig. 5 is asectional view on aplane indicated by the line V V, Fig. 4.. Fig. 6 is asectional detail view showing the forming-matrices, the plane ofsecplane indicated by the line VII VII, Fig. 8.

Fig. 8 is a sectional detail view of the shifting carriage with aportion of the cylinder secured thereto, the plane of section coincidingwith the axis of the' cylinder. Figs. 9, 10, and 11 are detail views ofthe turningstem and its operating parts. Figs. 12 and 13illustrateportions of the turning'devices in different positions.

In the practice of my invention one-half of the matrices employed forshaping the axle or other article are formed in a die-block 1,

which issecured on a suitable anvil-block 2.

The other portions of the matrices are formed in a block 3, secured tothe movable head 4 of the steam-hammer or other suitable operatingmechanism. These matrices are pref- Serial No. 104,253. (No model.)

erablyarranged in accordance with the successive operations on the axle,so that the axle may be shifted without reversal of its movement fromone matrix to the other or others. On opposite sides of the anvil-blockare arranged suitable stands or frames 5, provided with guides 6 forcarriages 7, adapted to be shifted along the stands by means offluid-pressure cylinders 8, so as to carry the axle or other articlefrom one shaping-matrix to the other, as hereinafter described.Fluidpres'surecylinders9'are secured to the car riag'esf7, withtheir-"axes parallel with the axes of the matrices in which the axlesare to be shaped. The piston-rods 10 of these cylinders are secured toslidingblocks 11, adapted to move along guides 12, formed on thecarriages 7 and in line vertically with the axes of the cylinders.Bearings 13 are secured to the carriages 7 on the side opposite thepistons,and in these hearings are mounted rotating heads 14, throughwhich pass stems 15, having their outer ends secured to the slidingblocks 11 with freedom of rotation. The rotating heads the axles orother article to one side of the axes of such article, so that when thestems 15 are rotated, as hereinafter described, an axial rotation of theaxle or other article will be effected, so as to present new surfaces tothe walls of the shaping-matrices. In order to heads 14 are providedwith curved arms l8,and fingers 19 are pivotally connected to brackets20, secured to the upper or'movable die-block 3. The operation oftheseparts to efiect a rotation of the stem 15 and the article beingforged is clearly illustrated in Figs. 12 and 13. As therein shown,th'e'finge'rs 19 will as the upper die-block descends strike against.the arms 18 and be turned on their pivotal points until they havepassed below the arms, when the fingers will resume or drop to normal orhorizontal position below the arms 18, as shown in the lower view inFig.12 and 9 1 effect the rotation" of the stem and axles, the

the upper view in Fig. 13. As the die-block 3 moves up the fingers 19will catch under the arms 18 and lift them, thereby turning the heads14.- and the stems 15 through any desired length of are, and as thedie-block reaches the upper limit of its movement the fingers will passoff from the arms, so as to permit the arms and heads to rotate backagain to normal position so soon as the studs or pins 17 are withdrawnfrom engagement with the axle or other article.

It is necessary in order to shift the axle from one matrix to anotherthat the axle should be lifted clear of the matrix in the lowerdie-block previous to any material lateral movement. To this end theguides'6 are provided with curved grooves 21, into which project pins22, secured to the buggy 7 and preferably provided withantifrictionrollers. These grooves are so shaped that when the carriage7 is shifted by fluid-pressure in the cylinders 8 its initial movementwill be vertical, so as to lift the axle from the matrix, it beingunderstood that the studs 17 on the stems 15 are in engagement with theends of the axle. After this initial vertical movement of the carriageit is moved horizontally to bring the axle in position over the nextmatrix, whereupon the carriage will drop, so as to allow the axle toenter into the next matrix.

In operating my improved mechanism a heated blank is placed in one ofthe matrices, as a, in the lower die-block and the upper die-blockcaused to descend to shape the blank, and after one, two, or moreshapingblows of the upper die-block the stems 15 on the buggy 7, whichhas been previously adjusted to bring the stemsinto alinement with thematrix a, are forced inwardly, so that the studs or pins 17 will engagethe ends of the blank. After this engagement of the studs with the axleeach upward movement of the upper die-block will impart a partialrotation to the stems 15 and the blank carried thereby, so that on eachstroke of the upper die a new portion of the blank will he presented forreduction. v\Vhile the stems are forced inwardly, so that the studs orprojection 17 are. in engagement with the blank, the friction of theparts will prevent any rotation of the stems and axle by the weight ofthe arms 18 on the rotating head. Hence if it is desired that the blankshould be rotated after each stroke the valve mechanism 23, controllingthe flow of fluid-pressure to the cylinders 9, should be operated sothat the stems 15. will be withdrawn as the upper die-block descends. Bythis withdrawal of the stems 15 the heads 1-1 and the stems can berotated back by the weight of the arms 18, so that on the next upstrokeof the upper die-block the heads and stems can be rotated; but beforesuch upstroke of the upper die-block the stems should be forced inwardlyby the proper manipulation of the valve mechanism 23, so as to cause theprojection 17 to engage the ends of the axle. After the desired reduction has been effected in any one of the matrices the stems 15 areforced inwardly, so as to engage the axles, and the carriage 7is thenshifted along its guideways by properly shifting the valve mechanism 24so as to shift the partiallyformed axle from one matrix to the other.

It will be seen by reference to Fig. 2 that brackets 20, carryingtheturning-pins19, correspond in number to the matrices employed, so thatthe turning of the article, as is necessary to avoid finning, may beeffected while being operated on or shaped in each matrix. It ispreferred to withdraw the stems 15 before each blow of the upperdie-block in order to avoid any injury to such shifting and turningmechanism.
